mean primitive | NetLogo Dictionary

mean

Mean reports the mean, or average, of the numeric values in a given list. (The mean is calculated by summing all the values, then dividing by the total number of values.) For example,

ask turtles with [ size >= mean [ size ] of turtles ] [ 
    set color red ]

would turn all the turtles who are larger than average red.

turtles-own [ test-score ]

; this model is a class of students who have taken a test
; the students who scored above average will become happy

to setup
  clear-all
  create-turtles 20 [ set shape "person student"
    set color red
    move-to one-of patches
    set test-score random-float 10]
  ask patches [ set pcolor green ]
  update-plots
end

to above-average?
  ; the class has a nice teacher who rounds up test scores, using ceiling
  if rounding = "round-score-up" [
    ask turtles [
    set test-score ceiling test-score
    if test-score >= mean [test-score] of turtles
      [ set shape "face happy" ] ] ]
  ; the class has a mean teacher who rounds down test scores, using floor
  if rounding = "round-score-down" [
    ask turtles [
    set test-score floor test-score
    if test-score >= mean [test-score] of turtles
      [ set shape "face happy" ] ] ]
  ask turtles [
    set xcor test-score ]
  update-plots
end

; arrange on pxcor my test, have a turtle mark average
; set scores out of 10 to show more difference
; add histogram
